10-BETA1: USB keyboard lost connection

[Wei Guo]

Hi list,

I have a USB keyboard connected to a machine running 10-BETA1 #0
r257155. This morning I tried to use the keyboard but found that it had
lost its connection to the server which is an IBM X3100 M4. I checked
the system log but found nothing strange, it seemed everything has been
working fine. I tried to reconnect the keyboard but it didn't work. I
had to reboot the machine and then the USB keyboard worked again. I
don't know if this is a bug, so I posted here just for your information.

regards!
